This paper accurately locates real data through statistical analysis of NSP mode files,analyzes the structure,encoding features,and influencing factors of WAV mode files;fully considers the number of channels,sampling frequency,and PCM sampling bits to realize the conversion of different mode formats,and designs a sig-nal analysis system based on audio multimodal research.The experiment conducts a comprehensive comparative a-nalysis from the aspects of file internal code,file parameter information,signal acoustic waveform and subjective auditory perception to verify the effectiveness and practicality of the system.
